Abstract: In order to explore the combination of undergraduates practical education and the actual needs of enterprises,and to improve the experimental teaching effect of high-frequency circuits,this paper proposed the introduction of fault tree analysis in high-frequency circuit experimental teaching to solve the experimental problems.The practical application of fault tree analysis method in high-frequency circuit experiment is introduced through an example.And corresponding implementation management methods are developed for the method to play its full role in experiment teaching.Practice shows that the introduction of the analytic method enable students to change from passive to active.Not only helps students to systematically understand and master the complex system,but also helps to train students’ abilities to analyze problems synthetically.The high frequency circuit experimental teaching activities received good results,and it is worth to be prompted.
